When I first started flying turbines, I was flying a 24lb. Hotspot with a Ram 500 (12# on a good day). That was .5 to 1 thrust ratio. If you're 22lbs. dry and with a gallon of kero, you may be just slightly under 30lbs; but worst case if it is 30lbs, you'll be around .58 to 1. Are you at sea level? This will make a huge difference. If you are sea level you will be fine, it will just take a circuit or so to get "on step".
